Brief summary

This project aims to evaluate the sensitivity and specificity of combined blood multi-gene methylation and fecal biomarkers for pan-digestive tract cancer screening, so as to establish a novel technical system for the early diagnosis of pan-digestive tract cancers.Individuals scheduled to receive digestive tract endoscopy are enrolled. Blood and stool samples are collected prior to endoscopic examination for detection of blood multi-gene methylation, fecal immunochemical test (FIT) and calprotectin. Endoscopic procedures are then performed. Following completion of baseline endoscopic screening, all enrolled participants will be followed up for 5 years. The primary endpoint of this study is the sensitivity and specificity of blood multi-gene methylation combined with fecal biomarkers in screening for pan-digestive tract cancers.

Inclusion criteria

* 1.Subjects aged 45-74 years at enrollment; 2.Scheduled to undergo digestive tract endoscopic screening; 3.Agree to receive five-year follow-up in accordance with the study protocol; 4.Willing to provide written informed consent.

Exclusion criteria
